Today, ultra-processed foods have become a part of our daily lives. These products, from packaged meals to ice-cream and bread in a package, stay fresh longer. However, research suggests that they could be harming the gut microbiome.
In the human body, trillions of bacteria live. The gut microbiome is a system that supports digestion, immune function, metabolism and brain functions. It becomes stronger and more stable the more it is diverse.
The addition of additives to ultra-processed foods raises concerns
Foods that are ultra-processed often include emulsifiers and artificial sweeteners. They may also contain preservatives or food colours.Emulsifiers help water and oil mix, for instance. These ingredients keep cakes, bread, and ice cream moist, even after weeks.
They are found in thousands of products at supermarkets. Scientists are now questioning their effect over time on the gut bacteria, even though food safety agencies have approved them as safe for chemical and toxicity.
Some additives, according to researchers, may disrupt the balance of bacteria in the gut. Studies show that emulsifiers can weaken mucus layers which separate bacteria and the intestinal wall.
Researchers link Emulsifiers with Inflammation and Disease
Researchers gave mice small quantities of emulsifiers in controlled experiments. These additives moved gut bacteria towards the intestinal wall. The change in the environment triggered an inflammation. Mice already prone to digestive disorders developed more severe symptoms.
Mucus in the gut serves as a protective layer. Chronic inflammation may result when bacteria penetrate this mucus layer. Chronic inflammation can increase the risk for inflammatory bowel diseases and metabolic disorders.
